xperiment 1: a) Determine the control limits for your control chart to three decimal places. b) Generate 200 random subgroups of size 10 from a N(90, =15) distribution and compute the sample average for each of the 200 subgroups. c) Out of the 200 subgroups generated, determine the first subgroup average to go out-of-control. Denote this subgroup number by RL1. This is the run length for the first experiment. Run length cannot be zero, so if none of the 200 values are out-of-control, ignore the data set and generate 200 new subgroups of size 10. Repeat as necessary to obtain RL1. d) Repeat the above procedure (parts b
